Output from a numerical model of the ocean beneath Larsen C Ice Shelf, Antarctica
GB/NERC/BAS/PDC/01605

Summary

Abstract:
This dataset contains output from a hydrodynamic model of the ocean in the Larsen C Ice Shelf (LCIS) cavity and a nearby area of the western Wedell Sea. Simulations were run using the MITgcm numerical ocean model and included an ice shelf with steady thickness. A new LCIS bathymetry was used in the simulations, referred to as the 'Brisbourne' bathymetry. The data provided here includes these geometry grids and ocean velocity and basal melt rate fields output from the final year of an arbitrary 10-year simulation, or a 6-month extension run. Calculated marine ice fields beneath the ice shelf based on the simulation's melt rate results are also included. In addition, output from several simulations using different initial and boundary ocean temperature conditions and runs with different cavity geometries are also provided.
